16. Protection Control
16.1 Protection Control for All Operations
16.1.1 Restart Control (Time Delay Safety Control)
 The Compressor will not turn on within 3 minutes from the moment operation stops, although the unit is turned on
again by pressing OFF/ON button at remote control within this period.
 This control is not applicable if the power supply is cut off and on again.
 This phenomenon is to balance the pressure inside the refrigerant cycle.
16.1.2 Total Running Current
1 When the outdoor unit total running current (AC) exceeds X value, the frequency instructed for compressor
operation will be decreased.
2 If the running current does not exceed X value for 5 seconds, the frequency instructed will be increased.
3 However, if total outdoor unit running current exceeds Y value, compressor will be stopped immediately for
3 minutes.

16.1.3 IPM (Power transistor) Prevention Control
 Overheating Prevention Control
1 When the IPM temperature rises to 120°C, compressor operation will stop immediately.
2 Compressor operation restarts after 3 minutes the temperature decreases to 110°C.
3 If this condition repeats continuously 4 times within 20 minutes, timer LED will be blinking (“F96” is indicated).
 DC Peak Current Control
1 When electric current to IPM exceeds set value of 16.0 ± 2.0A (Z20/25/35/42VK) and 30.0 ± 3.0A (Z50/71VK),
the compressor will stop operate. Then, operation will restart after 3 minutes.
2 If the set value is exceeded again more than 30 seconds after the compressor starts, the operation will
restart after 1 minute.
3 If the set value exceeded again within 30 seconds after the compressor starts, the operation will restart after
1 minute. If this condition repeats continuously for 7 times, all indoor and outdoor relays will be cut off, timer
LED will be blinking (“F99” is indicated).
16.1.4 Compressor Overheating Prevention Control
 Instructed frequency for compressor operation will be regulated by compressor temperature. The changes of
frequency are as below.
 If compressor temperature exceeds 103°C, compressor will be stopped, occurs 4 times per 20 minutes, timer
LED will be blinking. (“F97” is indicated.)
